Without Clams With Clams

  1. You're paying tax on a sale you never made.

    A move between your own wallets gets booked as a sale, and you pay tax on it.

    Transfers between your own wallets are never booked as sales.

  2. Your entire financial history sits on someone else's server.

    Every address, xpub, and transaction is one breach away from going public.

    Your financial history stays on your machine or your own server.

  3. You can't prove your books balance.

    Without double-entry, a matching wallet total proves nothing.

    You can prove your books balance, line by line.

Why Clams is different

Specialization

Bitcoin-native

Built for multisig and the complex transactions legacy tools choke on.

  • Reconcile multisig wallets automatically. No manual matching.
  • Account for channel opens, closes, and force-closes, not just payments.
  • Handle on-chain fees and change outputs without inflating gains.
View supported wallets →
Precision

Books that hold up to an audit

Double-entry accounting. Automated reconciliation. Balance tracking across all wallets, current to your last sync.

  • Auto-categorization with manual override
